Context

The Uttar Pradesh government has recently embarked upon a scheme to take the unique culture of its ethnic Tharu tribe across the world.

It is about connecting the Tharu villages in the districts of Balrampur, Bahraich, Lakhimpur, and Pilibhit bordering Nepal, with the homestay scheme of the UP Forest Department.
The idea is to offer tourists an experience of living in the natural Tharu habitat, in traditional huts made of grass collected mainly from the forests.
It will encourage villagers to acquaint them with aspects of safety and cleanliness, and with the rules of the forest.
The intention is to put Tharu villages on the tourism map and to create jobs and bring economic independence to the tribal population.

The community belongs to the Terai lowlands, amid the Shivaliks or lower Himalayas.
The Tharus live in both India and Nepal.
In the Indian Terai, they live mostly in Uttarakhand, Uttar Pradesh, and Bihar
Most of them are forest dwellers and some practice agriculture.
Members of the tribe survive on wheat, corn, and vegetables are grown close to their homes.
A majority still lives off the forest.

They speak various dialects of Tharu, a language of the Indo-Aryan subgroup, and variants of Hindi, Urdu, and Awadhi.
In central Nepal, they speak a variant of Bhojpuri, while in eastern Nepal, they speak a variant of Maithili.
Tharus worship Lord Shiva as Mahadev.
Most Tharutribals consume alcoholic beverages, and some eat beef.
